Condensation
Condensation is the process by which a gas changes into a liquid. This transformation occurs when the gas loses heat energy and its particles slow down, coming together to form liquid droplets.
Explanation:
When a gas cools down, its particles lose energy and slow down. As a result, the particles move closer to each other and start to attract one another. This attraction causes the gas particles to come together and form liquid droplets. This process is called condensation.
Key Points:
- Condensation is the opposite of evaporation, which is the process of a liquid changing into a gas.
- The temperature at which condensation occurs is known as the dew point.
- Condensation is a common process that happens in our everyday lives. For example, when you take a hot shower and the bathroom mirror becomes foggy, it is because the water vapor in the air has condensed on the cooler surface of the mirror.
- Clouds are formed through condensation. When warm air rises and cools, it reaches its dew point and condenses to form tiny water droplets or ice crystals. These droplets or crystals come together to form clouds.
- Condensation is an important part of the water cycle. When water evaporates from the surface of oceans, lakes, and rivers, it rises into the atmosphere as water vapor. As the water vapor cools, it condenses and forms clouds. Eventually, the condensed water droplets fall back to the Earth as precipitation, completing the water cycle.
In conclusion, when a gas changes into a liquid, it is called condensation. This process occurs when the gas loses heat energy and its particles slow down, coming together to form liquid droplets. Condensation is an essential part of the water cycle and is responsible for the formation of clouds and precipitation.

When gas changes into liquid, it is called:a)Meltingb)Solidificationc)...
The correct answer is D: Condensation.
Condensation is the process in which a gas changes into a liquid. This occurs when a gas is cooled to its dew point or when it comes into contact with a cooler surface, causing the gas molecules to lose energy and come closer together to form a liquid. This is commonly observed when water vapor in the air turns into liquid water droplets, such as on the outside of a cold glass or in clouds forming in the atmosphere.
The other options refer to different phase changes:
- Melting (A) is the process by which a solid turns into a liquid.
- Solidification (B), also known as freezing, is the process in which a liquid turns into a solid.
- Evaporation (C) is the process where a liquid turns into a gas.
